3.6.1.2  Origin/destination analysis of trips in Brisbane-Gold Coast-Sunshine Coast

Figure 73 shows trips in Brisbane-Gold Coast-Sunshine Coast by origin/destination (O/D), across road and public transport modes, in terms of DEC for 2011 and projected DEC for 2031. The O/D regions used here are SA3 regions as defined by ABS.359

The analysis shows that Inner Brisbane is the largest O/D for trips in the region and is projected to remain so. Between 2011 and 2031, some of the highest growth is forecast in the outer suburbs of Brisbane, with Jimboomba, Ipswich/Springfield-Redbank and Beaudesert all projected to increase at least four-fold.
